# Barium Aluminate [BaAl2O4] Molecular Weight Calculation

The molecular weight of Barium aluminate [BaAl2O4] is 255.2876768.

Barium aluminate [BaAl2O4] (CAS Registry Number: 12004-04-5) is an inorganic compound of three elements: Barium (Ba), Aluminium (Al), and Oxygen (O). The molecular weight of Barium aluminate [BaAl2O4] is 255.2876768 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of all its elements.

# CALCULATION PROCEDURE: Barium Aluminate [BaAl2O4] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in a Barium aluminate molecule.
From the chemical formula, you will know different atoms and their number in a Barium aluminate molecule. The chemical formula of Barium aluminate is BaAl2O4. From the chemical formula, you can find that one molecule of Barium aluminate consists of one Barium (Ba) atom, two Aluminium (Al) atoms, and four Oxygen (O) atoms.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Barium (Ba): 137.327 (Ref: PubChem-56, Ciaaw-barium)
Atomic weight of Aluminium (Al): 26.9815384 (Ref: ciaaw-aluminium)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)

Step 3: Calculate the molecular weight of Barium aluminate by adding the total weight of all atoms.

Number of Barium (Ba) atoms in Barium aluminate: 1
Atomic weight of Barium: 137.327
Total weight of Barium atoms in Barium aluminate: 137.327 x 1 = 137.327

Number of Aluminium atoms in Barium aluminate: 2
Atomic weight of Aluminium: 26.9815384
Total weight of Aluminium atoms in Barium aluminate: 26.9815384 x 2 = 53.9630768

Number of Oxygen (O) atoms in Barium aluminate: 4
Atomic weight of Oxygen: 15.9994
Total weight of Oxygen atoms in Barium aluminate: 15.9994 x 4 = 63.9976

Step 4: Calculate the molecular weight of Barium aluminate by adding up the total weight of all atoms.

Molecular weight of Barium aluminate: 137.327 (Barium) + 53.9630768 (Aluminium) + 63.9976 (Oxygen) = 255.2876768

So the molecular weight of Barium aluminate is 255.2876768.
